Question

What does the vertical component of a phasor give at any instant?

Options

• The phase angle between voltage and current

• The peak value of the AC quantity

• The instantaneous sinusoidally varying value of the AC quantity

• The angular speed of the phasor

Answer 1

The vertical component gives the instantaneous value of the voltage or current represented by the phasor. As the phasor rotates, this component varies sinusoidally.
